So do you have any ready-made test sets including both query files and
data/config for the authoritatives?
This is where it falls short, I presume each implementor has its own
dataset and it's hard to tell how much it represents the reality.
I'd like to have something that I can download, set up according to
the spec and let the magic happen, but I guess there's no free lunch.
